Leather breaks the full-metal line and gives the 42.5mm case a more formal setting. The deployant clasp retains a finished attachment, but the wrist reads differently from a rose-gold-toned bracelet model. The custom manual-wind movement also suits a buyer who enjoys winding a mechanical watch as part of wearing it.
Leather gives the open display a formal pause: the moving carriage remains the focal point, while the strap avoids adding another reflective surface. That makes the configuration easier to wear with a jacket or dress shirt. The rubber sibling keeps the same dial idea but shifts the balance toward travel and casual clothing.
Before dispatch, our QC team reviews the tourbillon carriage motion, blue dial finish, plated bezel, leather attachment, and clasp.
